Specification of Letters Patent.

Patented llltar.. 9, TM5..

To alli/:710m it may concern Be it known that Asarn M. HIGLEY, a citizenof the United States, residing` at Cummings, in the county of Atchisonand State of Kansas, have invented certain new and useful Improvementsin Drag-Saws; and l do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to new and useful improvements in drag saws andthe object in view is to produce a simple and eilicient device of thisnature so arranged that the log or other article to be sawed may bgripped and securely held while the saw is operated.

Another feature of the invention comprises a drag saw in which anauxiliary handle may be attached to the apparatus so that the saw maycut in a horizontal position.

The invention comprises various details of construction and combinationsand arrangements of parts which will be hereinafter fully described,shown in the accompanying drawings and then specifically defined in theappended claim.

I illustrate my invention in the accompanying drawings, in which: u

Figure l is a perspective view of my improved drag saw. Fig. 2 is a sideelevation, and Fig. 3 is a perspective view showing the adjustment ofthe parts to enable the saw to be operated in a horizontal plane.

Reference now being had to the details of the drawings by letter, Adesignates the drag saw having a plate B secured thereto from whichprojects a pin C. The operating lever is designated by letter D .and 1spivotally connected through the medium of the pin D with the bars Ewhich are fastened to said plate B, one upon each side of the lever.rThe lever D has a pin F projecting from one side thereof, forming ahandle which, together with the handle C, may be utilized for adjustingthe saw or starting the same as an operator commences to cut a log orother article.

A bar, designated by letter H, is pivotally connected to the lever andtelescopes within a. shell T which carries a grooved anti-frictionroller, adapted to rest upon the rear edge of the saw. Said bar H may beheld within different adjusted positions within the shell and the rearend of said bar has a spring 0 bearing against the same, while its.other end engages the handle, said spring being provi-ded for thepurpose of holdingl said roller upon the rear edge of the saw, as willbe readily understood, to guide the latter and press down upon the sawwhile it is in operation.

A bar R has pivotal connection through the medium of the pivot R withthe lever D and said bar carries pins X and T upon which the bar T4 ismounted. A lever X is pivotally mounted upon the pin X and the grippingjaws T are mounted upon the pivotal pin T', while a third gripping jaw Sis pivotally mounted upon a pin T2 carried by the bar T". Springs X2 arefastened at corresponding` ends to the upper ends of the jaws T, whiletheir other ends are fastened to the lever X upon opposite sidesthereof. Projecting from the edge of one of the jaws T is ay lug T3,shown clearly in dotted lines in Fig'. 2 of the drawings, and to whichthe links S are pivotally connected which in turn are pivotallyconnected to the upper end of the shank portion of the gripping jaw S.

A toothed segment W is fastened to the bar R, the teeth of which areadapted to be engaged by the edge of the lever X to hold the variousgripping members in or out of engagement with the log or other articlebeing sawed.

In the modified form of saw, in which it is held in a horizontalposition and is illustrated in the drawings, an auxiliary handle J isused which has a shank portion L, the ends of which are bent laterallyas at L and adapted to be held by means of bolts L2 to the lever D, asshown.

In applying the device, the operator places the pointed ends of thegripping jaws in contact with the log and, by pulling upon the lever Xputting the springs X2 under tension, the points at the ends of the awsT may be caused to penetrate the log and, as the shank portion of thejaw carrying the lug T3 tilts upon its pivot, the toggle link connectionintermediate the same and the upper end of the shank portion of the jawS will cause the point upon the latter to engage the' log in the mannershown in Fig. 1 of the drawings, thus securely gripping and holding theframe upon the log. It will be understood that the springsX2 are ofsufficient strength to cause this gripping action when the lever isswung in the manner described. j j

By the provision of a drag saw made in accordance with my invention, itwill be noted that a simple and ellicient device is afforded whereby anarticle being sawed may be securely gripped by the members shown Whilethe saw is operated to cut the log or other article, the grooved pulleyriding upon the upper edge of the saw serving as a means for guiding thesame and causing a slight pressure upon the saw, sutlicient to effectthe sawing. Y

When it is desired to adapt the saw to cut in a horizontal plane, theauxiliary handle is attached as shown in the drawings, thereby affordingconvenient means for reciprocating the saw.

What I claim to be new is A drag saw apparatus comprising a bar, a sawand means for reciprocating the latter, a lever pivotally mounted uponthe bar, gripping jaws arranged side by side and pivotally mounted uponthe bar, brackets projecting from the opposite sides of the lever,springs secured to the upper portions oi the shanks of said grippingjaws, the shank of one of said jaws having a lug thereon, a thirdgripping jaw pivotally mounted upon the bar and links pivotallyconnecting the upper end thereof with said lug, as set forth.

In testimony whereof I hereunto aliix my signature in presence of twowitnesses.
